Abstract

The diode-pumped rare gas laser (DPRGL) has been suggested as a potential high-gain, high-energy laser which requires densities on the order of 10¹³ cm⁻³at pressures around 1 atmosphere for efficient operation. Argon 1s₅ number densities have been measured in micro-hollow cathode discharges with electrode gaps of 127 and 254 μm and hole diameters from 100-400 μm. The dependency of the metastable argon (1s₅) density on total gas pressure, electrode gap distance and hole diameter were explored. The measured densities were all in the range of 0.5 − 2 × 10¹³ cm⁻³ with the 400 μm hole diameters being the lowest.
